2.1 Theory of Operation for the INA209 Test Board Hardware
Figure 3 shows the block diagram of the INA209 test board. The INA209 test board functionality is
relatively simple. It provides connections to the I
2
C™ interface and general-purpose inputs/outputs
(GPIOs) on the USB Dig platform. It also provides connection points for external connection of the shunt
voltage, bus voltage, and GND on the system being measured.
